NOTE When the switch is in the Off position, the
inverter draws no current from the battery. When
it’s in the On position, but no power is being
supplied to the load, the inverter draws less than
500 milliamperes from the battery. This is low
current draw. It would take more than a week to
discharge a 100 ampere-hour battery at this rate
depending on the age of the battery.
Power and Protection Indicators •
The Power and Protection Indicators include a green light,
a red light and an alarm.
Green Light
Power On– The green light should remain On steady.
Red Light and/or Alarm
Current Overload – The red light will turn On momentarily,
then the inverter will shutdown. The inverter will
continue to check for appropriate current levels
while trying to restart the load.
Voltage Overload – The red light will blink and the
inverter will shutdown. The inverter will continue to
check for appropriate voltage levels while trying to
restart the load.
Voltage Shortage – As a warning that the voltage is
getting low, the internal alarm will sound. When the
voltage is too low, the inverter will shutdown and the
red light will turn On. The inverter will continue to
check for appropriate voltage levels while trying to
restart the load.
Temperature Overload – The red light will turn On
momentarily, then the inverter will shutdown. The
inverter will continue to check for appropriate
temperature levels while trying to restart the load.
NOTE A momentary sound of the internal alarm
and/or flash of the red light is normal at start up.

Operation Operating Limits
Operation
Operating Limits •
Power Output
The inverter can deliver 800 watts for about 60 minutes.
The inverter must cool for 15 minutes before it can
resume operation at 800 watts. Note: The wattage
rating applies to resistive loads.
The inverter will operate most AC loads within its power
rating. Some induction motors used in freezers, pumps,
and other motor-operated equipment require very high
surge currents to start. The inverter may not be able
to start some of these motors even though their rated
current draw is within the inverter’s limits. The inverter
will normally start single phase induction motors rated
at 1⁄2 HP or less.
Input Voltage
The inverter will operate from input voltage ranging
from 10 volts to 15 volts. Optimum performance will
occur when the voltage is between 12 volts and 14 volts.
If the voltage drops below 10.5V+/-0.3V, an audible
low battery warning will sound. The inverter will shut
down if the input voltage drops below 9.5V+/-0.3V. This
protects the battery from being over-discharged. It will
restart when the input voltage exceeds 12V+/-0.3V.
The inverter will also shut down if the input voltage
exceeds 15.75V+/-0.75V. This protects the inverter
against excessive input voltage. Although the inverter
has protection against over-voltage, it may still be
damaged if the input voltage were to exceed 16 volts.
